TEMPORARY BINDER.

SPECIFICATION forming part of Letters Patent No. 788,853, dated. May 2, 1905.

Application filed January 26, 1905- Serial No. 242,767.

To uJZZ whom it may concern:

Be it known that I, LIBORIUS SENGE, a citizen of the United States, residing at Crescent Springs, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Temporary Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specifieation.

, My invention relates to that class of binding-files or loose-leaf binders which are now generally known to the trade as post-binders, wherein any convenient number of letters, bills, or other sheets are held until they are ready to be permanently bound up or filed away. These binders usually consist, as in the present instance, of a base-piece from which extend at right angles thereto and near the top edge thereof two filing-rods, upon which the leaves or other papers to be filed are strung, and which are secured in place by a sliding top piece or follower, usually in the form of a hinged book-cover, and provided with means for locking the same to the filingrods when pressed down upon the leaves and for unlocking the same to permit it to be raised and removed from the rods to introduce new leaves or change their relative positions on the rods; and it has for its object the production of a binder of this class which is cheap and simple in its construction and exceedingly eliicient in action and in which the binding member is so slotted that it can be slipped bodily from the rods without having to be slid upover their tops and can be replaced in the same manner and then be clamped to the rods, all as will be hereinafter more fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a binder embodying my invention and partially filled with bound sheets. Fig. 2 is an enlarged perspective of the bottom plate and clamping mechanism. Fig. 3 is an inverted perspective of the cover or housing which fits over the bottom plate.

The same numerals of reference are used to indicate identical parts in all the figures.

As is customary in this class of binders, 1

is the back or base, to which is flexibly secured at its upper edge a metal strip 2, into which the lower ends of two binding-posts 3, which are parallel to each other and at right angles to the metal strip, have their lower ends secured by riveting or by beingscrewed thereto. Thepapers to be bound have their upper ends perforated to slip over the posts 3, and a cover 4, having a hinged upper extension 5, with slots 6 through it to slip over the posts, rests on the top of the papers, as seen in Fig. 1. These papers may be letters, bill-heads, order-sheets, or, in fact, any kind of papers that it is desired to file in a temporary binder and afterward when the binder is full to be removed to a permanent vbinder or transfer-case.

By providing the slots 6 in the upper edge of the cover 5 it may be drawn down off of the posts without having to be slid up and lifted off of them when it is desired to add papers to or remove them from the file.

It is necessary in a file of this character, especially Where the top cover is slotted and slipped off of the posts and a large number of papers are to be filed, that there should be clamping mechanism of some sort to grip the posts and hold thetop cover securely down upon the papers, and I have provided a very simple and el'licient clamping mechanism for this purpose. Upon the top of the extension 5 of the cover is screwed or otherwise secured a flat plate 7, with slots 8, Fig. 2, in its upper edge registering with the slots 6 and in line with the posts 3, and upon this plate are two pivoted gripping-dogs 9, pivoted, as at 10, adjacent to the outer edges of the slots 8. Between the jaws 9 are two flat metal pieces 11, whose ends adjacent to the jaws correspond in shape to the inner ends of the jaws, with a rounded outer portion terminating in a notch or recess 12 opposite a corresponding notch or recess in the jaws. There is a space between the pieces 11, in which is pivoted to the plate 7 a cam 13, bearing against the inner ends of the pieces 11 and provided with an operating handle or thumb-piece 14, which projects inward beyond the plate 7 and through a slot 15 in a cover or housing 16, which fits snugly over the jaws and pieces 11 and serves as a guide for the latter and is screwed down upon the plate 7, as at 17. This housing is clearly illustrated in Fig. 3 and is provided at its upper edge with slots 18, registering with the slots 8 and 6.

When the cam 13 is turned in one direction, the slides 11 are free to move toward each other and the jaws 9 are free to swing outward to permit the free passage of the posts 3 through the slots and into the recesses 12, and the cover is then pressed firmly down upon the papers, and the lever 14 is vibrated to turn the cam and cause the slides 11 to be spread apart, by which spreading action their outer ends engage the tail ends of the jaws and cause them to swing inward and firmly grip the posts with a pinching. action, which prevents the cover from being slipped up on the posts or pulled oflj of the same until the cam has been again vibrated to release the parts, as will be readily understood.

Where desired, the cover 4 may be omitted and any ordinary protecting sheet of paper, perforated and slipped over the posts,may take its place.

Having thus fully described my invention, I claim- 7 1. In a temporary binder, the combination of a bottom filing-base, a pair of filing-posts extending therefrom at right angles thereto and parallel to each other, a clamping-piece with slots in its upper edge registering with the binding-posts, slides upon said clampingpiece provided with gripping-jaws adjacent to said slots, pivoted clamping-jaws in line with said slides and likewise adjacent to said slots, a covering for said slides and gripping-jaws secured to the clamping-piece and provided with slots registering with the slots in the clamping-piece, and a cam with a projecting operating-handle confined between the adjacent ends of the slides, substantially as described.

2. In a temporary binder, the combination of a bottom filing-base, a pair of filing-posts extending therefrom at right angles thereto and parallel to each other, a clamping-piece with slots in its upper edge registering with the binding-posts, slides upon said clampingpiece provided with gripping-jaws adjacent to said slots, pivoted clamping-jaws in line with said slides and having tail extensions coacting therewith, said jaws being likewise adjacent to said slots, a covering for said slides and gripping-jaws secured to the clamping-piece serving as a guide for the slides and provided with slots registering with the slots in the clamping-piece, and a cam with a projecting operating-handle confined between the adjacent ends of the slides, substantially as described.

3. In a temporary binder of the character described, the post clamping and releasing mechanism comprising a plate 7 with slots 8, gripping-jaws 9 pivoted adjacent to said slots, slides 11 with gripping-jaws at their outer ends which engage, the tail ends of the pivoted gripping-jaws, a pivoted cam interposed between the inner ends of the slides 11, a guidehousing 16 provided with slots 18 and 15 covering the aforesaid slides and jaws and secured to the plate 7, and an operating-handle for the cam projecting from the guide-housing, substantially as described.

LIBORIUS SENGE.
